years ago when I was working we had a tool that was used to remove screws. it was like a rachet type tool that use we used a hammer and hit the end of it and it would turn to lossen up or put in a screw. worked awful well for removing rusted old screws. anyone know what I might be talking about and what it is called. thanks norm
 
Impact driver is what I call them. Real handy on taking screws out of aluminum. I guess the cordless screw guns are called impact drivers too.
 

I bought an impact driver from J.C. Whitney way back in about 1971 or so. A few months earlier I had purchased a used, 1968 Honda CL-350. That impact driver was crucial for removing the screws from aluminum.
 
Then replace 'em with socket head screws;done it with every Jap bike.My 68 Cl 350 was only
new bike I ever owned!
 
They are not in extra tight it is the fact that metal bolts/screws in aluminum react to each other so it makes them hard to remove

Funny you say that, I bought one for my Yamaha in 1968 for the very same reason. First new tool I ever bought. Still have it and I still use it.
 
I guess the most extreme example of over tightened bolts (nuts in this case) were the valve adjusting lock nuts on the Datsun 4 and 6 cyl OHC in the 70's.

From the factory, if they had never been adjusted, would have to pry the rocker off to get a box end on them with a cheater pipe.

Ridiculously tight!
 
Impact driver, seems like 40 years ago I used it every other day but can't remember what for now.

Maybe I just never got to see one that hadn't been adjusted, 'cuz I don't remember that. Certainly I remember having to adjust them a lot, those soft bronze intake seats were always beating in so the intake was too tight. I also remember you couldn't overheat one, not even once. Even if you got lucky, didn't warp the head or collapse the oil rings, that oil restrictor jet at the top of the oil passage in the block would plug up with burnt oil and so the cam and lifters wouldn't get oil. On those machines that meant buy a new head, complete.
 
Hello pinball,

My impact is 1/2" drive. You also need to get impact bits,

Guido.
